Application filed November 25, 1910, Serial No. 594,138.

To all whom it 171 (13 concern:

Be it known that 1, vViLLiAM B. FENN, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio,have invented a certain new and useful improvement in Treating-Chambersfor Sterilizing-lvlachines, of which the following is a specification.

The object of this invention is to provide an improved means for.confining a vessel containing a material to be treatedas for example afood to be sterilized.

The invention is embodied in the constructioii hereinshown and describedand then pointed out in the claims at the end of the description.

1n the accompanyi g drawing Figure 1 illustrates partly in verticalsection and partly in elevation, a construction according to theinvention and Fig. 2 is a vertical section 01' the treating chamber anddevices therein.

In said drawing 1 designates a cylindrical chamber which is designed tobe fixed vertically. Said chamber contains a piston 2 and a piston-likehead The piston 2 and head 3 are secured on or are movable withreference to a rod or tube 4: extending upward through the head of thechamber. The members 2 and 3 are separated from each other by a space at4*. The chamber 1 is provided with fluid pressure conductor 5 at itsupper end through which pressure can be admitted or exhausted from thechamber above the piston, which a treating brid -steam for examplecan beadmitted to treat the contents of the vessel T containing the materialto be treated.

S designates a nozzle on the head 3 for penetrating the material in thevessel 7 said nozzle being in the form of a tube prefer ably laterallyperforated and connected with passages in the head so as to distributethe treating medium delivered, from the conductor 6 through thematerial.

9 designates a vertically standing and vertically stationary columnhaving thereon an annular enlargement 10 of piston form.

Surrounding the column at the region of the piston-like enlargement is acylinder 11 provided with packings at 12 and 13 to form fluid tightjoints above and below the piston-like enlargement. The cylinder iscapable 01" being reciprocated on the column. At the upper end of thecylinder is secured Specificationof Letters Patent.

and a conductor 6 through in connection therewith treating material, of

by bolts 14 a sleeve 15 of about the length of that portion of thecolumn which extends above the piston enlargement or preferably so thatwhen the cylinder is depressed to the limit of its down stroke the upperend of the column will be exposed to permit the vessel 7 to be slid ontothe upper end thereof by a horizontal movement. The upper end of thesleeve 15 is provided with seat 16 for the lower end of the chamber 1,said seat being provided with a soft packing 17 so that when the sleeveis moved up against the end of the chamber the vessel is fluid tightlyinclosed at that region. The lower portion or" the column is providedwith ducts 18 and 19 that open respectively above and below thepiston-like enlargement of the column but within the cylinder and thesupply ends of said ducts are at the exterior of said cylinder so thatby admitting a pressure fluid to the cylinder above the pistonprojection and exhausting the fluid below such projection the cylinderand the sleeve it carries can be elevated, and conversely by admittingpressure fluid below such projection and exhausting the fluid above thepiston the sleeve can be depressed. When the sleeve is elevated itsurrounds the vessel and when depressed the vessel is exposed forremoval. \Vith this construction the vessel is not vertically moved butremains at the horizontal plane of the seat at the upper end of thecolumn. After the sleeve has been moved up to inclose the vessel fluidpressure is admitted to the upper side of the piston 3 which depressesthe head and projects the treating nozzle into the contents of theressel containing the material to be treated, and at the same timebrings the opening 1* opposite the discharge end of the conductor (3.The admission of the treating material to and through the nozzle maytake place simultaneously with or at any time subsequent to the closingof the sleeve on the. chamber this being a matter of choice and to beregulated by the operator or bythe mechanism that may be provided forperforming that operation.

What I claim is:

1. In apparatus for treating materials, the combination with a chamber,and means for applying a a vertically. stationary column for supportinga vessel containing material to be treated, a sleeve movable on saidcolumn, and means for raising said sleeve against the aforesaid chamberto in close a vessel. supportedon said column.

2. In apparatus for treating materials, the combination with a chamber,and. means in connection therewith for applying a treating material, ofa vertically stationary column for supporting a vessel containingmaterial to be treated, a sleeve movable on said column, means'includinga cylinder movable on said (ZUlLH'I'lIl, a piston on said column withinthe cylinder and ducts for admitting and exhausting fluid pressure atopposite ends of said cylinder to elevate said sleeve against theaforesaid chamber to inclose a vessel supported on said column.

In apparatus for treating materials, the combination with a chamber, andmeans in connection there vith for applying a treating material, of avertically stationary column for supporting a vessel containing materialto be treated, a sleeve movable on said column, means including acylinder movable on said column, a piston on said column within thecylinder, and a duct lor admitting fluid pressure to an end of saidcylinder to cause the same to move said sleeve against said chamber toinclose a vessel supported on said column.

4. In apparatus lor treating materials, the combination with a chamber,and means in connection therewith for applying a treating material, of avertically stationary column for supporting a vessel containing materialto be treated, a sleeve movable on said column, means including acylinder movable on said column, and a piston on said column within thecylinder, said column provided with a duct for admitting fluid pressureto an end of said cylinder to cause the same to move said sleeve againstsaid chamber to inclose a vessel supported on said column.

5. In apparatus for treating materials, the combination with a chamber,and means in connection therewith for applying a treating material, ol avertically stationary column for supporting a vessel containing materialto be treated, a sleeve movable on said column and means including acylinder movable on said column and a piston on said column within thecylinder, said column provided with ducts for conveying a lluid pressureto the opposite ends of said cylinder to reciprocate the same withreference to said chamber.

(3. Tu apparatus for treating ll'ltlllGI'lEllS, the combination with achan'iber, and means in connection therewith for ap ')lying a treatingmaterial, ol a, vertically stationary column for supporting a vesselcontaining material to be treated, a sleeve movable on said. column,means for raising said sleeve against the aforesaid chamber to inelose avessel supported on said column and. means for lowerin said sleeve toexpose the ves-' 2: sel on said. column.

7. In apparatus for treating materials. the combination with a chamber,and means in connection therewith for applying a. treating material, ofa column for support ing a vessel containing material to be treated, asleeve fitting the said column, the said column and sleeve beingrelatively movable vertically, means for effecting relative verticalmovement between the sleeve and the aforesaid chamber to inelose avessel supported on said column and means for again effecting relativemovement between the sleeve and chamber to expose the vessel on saidcolumn.
